    Study Notes

    System Unit

    • The system unit is the main housing of a computer, containing the central processing unit (CPU), memory, and other essential components.

    Components Inside the System Unit

    • Common components inside the system unit include:
      • Motherboard
      • Power supply
      • Storage devices (hard drives, solid-state drives)
      • Memory (RAM)
      • Processor (CPU)
      • Cooling systems (fans, heat sinks)

    Motherboard

    • The motherboard is the main circuit board of a computer, connecting and supporting various components.

    Chip

    • In the context of computers, a chip refers to a small piece of silicon containing an integrated circuit.

    Integrated Circuit

    • An integrated circuit is a set of electronic components, such as transistors, resistors, and capacitors, etched onto a small piece of semiconductor material (silicon).

    Packaging Chips

    • Chips are typically packaged in computers using a protective casing, with pins or contacts for connecting to the motherboard or other components.

    Heat Sink

    • The function of a heat sink is to absorb and dissipate heat generated by computer components, such as processors, to prevent overheating.

    Non-Volatile Memory

    • Non-volatile memory is a type of memory that stores data without electrical current, even when the power is turned off.

    EPROM

    • The purpose of EPROM (Erasable Programmable Read-Only Memory) is to store data that can be erased and reprogrammed using specialized equipment.

    Measuring Memory

    • Memory is typically measured in units of bytes, with common sizes including kilobytes (KB), megabytes (MB), and gigabytes (GB).

    RAM

    • RAM stands for Random Access Memory, a type of volatile memory that temporarily stores data and applications while the computer is running.

    Processor Chip

    • The primary function of a processor chip is to execute instructions and perform calculations, controlling the flow of data and operations within a computer.

    Reprogrammable Memory

    • EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of memory that can be erased and reprogrammed repeatedly using electrical signals.
